Peeing more often will become a problem over time as essentially you're not emptying your bladder completely each time.

If you're prostate is enlarged then the first step is lifestyle changes to mitigate against the enlargement. That includes drinking less alcohol and less before bed, but also importantly losing weight if over weight and improving your diet to try and slow the increase in size. The evidence isn't great on preventing enlargement but prostate enlargement is associated with being overweight and poor diet.

Medication becomes needed if you start getting more severe symptoms. You could choose to take these earlier but they have side effects.

Finally if all else fails then surgery is needed to debulk the prostate. That is worth avoiding as much as possible due to the side effects - so lifestyle changes and earlier use of medication when it becomes needed are the best wya forward.

Im 32 and same issue. Went to doctor for an ultrasound because im a pilot and cant pee at work. I since learnt to sit down to pee, lean forward, and push into your bladder with your fingers. You can even kindve do it when standing up. I end up doing a second wee. This takes a few seconds longer and its helped me so much in life.

I dont have an answer to the question though haha

Was the exam with a general practitioner, or a urologist?

If a GP, I'd get checked by a urologist.

If a urologist, I'd probably ask for more information. I would want to know of any specific symptoms that might be treated as early warning signs, as well as organising an ongoing schedule of check-ups to monitor the size. It would be worth asking about treatment options as well.

One issue often overlooked with prostate enlargement is Nykturia. Nykturia causes sleep deprivation, sleep deprivation causes scores of other problems from cardiac issues to psychosis. I'd say ~ 3 times getting up during the night might be tolerable for most peope, > 5 times will cause problems.
